ASH SIFTER. v No 499,282. Patented June 13, 1893.

EMMETT OOON, OF ANN ARBOR, MICHIGAN.

ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 499,282, dated June 13,1893.

Application filed March 25, 1893- To all whom it may concern.-

Be it known that I, EMMETT CooN, a citizen of the United States ofAmerica, residing at Ann Arbor, WVashtenaw county, Michigan, haveinvented certain new and useful Improvements in Ash-Sifters, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This improvement relates to that class of ash-sifters provided with aremovable sieve hung on a swinging frame operated by a lever, and theinvention consists in the peculiar construction, arrangement andcombinations of parts hereinafter more particularly described and thendefinitely claimed.

In the accompanying drawings-Figure 1 is a plan of a sifter constructedaccording to my improvement. Fig. 2 is a vertical central section of thesame when the sifter is in action. Fig. 3 shows a similar section whenthe cinders and unburned coal are about to be discharged.

Referring now to the details of the drawings by 1etter-A represents abox having a drawer B in its bottom and provided with a door 0 hinged atc, and a knob D by which it may be fastened, either in an open or closedposition, by hooks E.

At F is shown a cover which is hinged at G (see Fig. 3).

A frame H is hung by links I in the box A, and upon this frame issupported the sieve J, which may be of any convenient form or material,but preferably square or oblong.

Pivoted to an arm K, extending from the end of the box, is a lever L,connected to the frame H by a link or pitman M passing through the endof the box. On the end of the sieve opposite the lever is a broad spoutN, whose object will be more fully hereinafter explained.

The operation is as follows: The top or cover F of the box is opened andset against an upright O on the side of the box, when the mixed ashesand cinders are dropped into the sieve J, and then the cover F is closeddown tightly, after which the lever is vibrated a few times and thus theashes are quickly sifted out of the cinders and unburned coals SerialNo. 467,539. (No model.)

and pass through the bottom of the sieve into the drawer B, from whencethey can be readily removed by withdrawing said drawer from the boxthrough the door 0 which should be opened for that purpose, and may befastened open by the upper hook E, when desired. When it is desired toremove the cinders, &o., from the sieve, the lever L is pushed as far aspossible to the right, which will lift the spout N upon the opposite enda of the box A, when by lifting the left hand end of the sieve, thecinders, 850., will pass out through the spout into any receptacleplaced to receive them. By this means the ashes may be quickly siftedand the cinders separated therefrom by the merest child and withoutcreating any dust or dirt. In order to prevent the spout N strikingagainst the top of the box when 1t is closed, the lever is so arrangedas to come in contact with the end of the top of the box, when it isdown, but when the top is open the lever can be given greater motion, asshown in Fig. 3.

In some cases I may use an additlonal screen as shown in dotted lines inFig. 2, by which the cinders may be separated into two sizes, which willalso make it more convenlent in separating clinkers as they willgenerally remain in the upper sieve.

What I claim as new is- 1. The combination with the box A, of theswinging frame H, lever L, connected to the frame, and sieve J, havingspout N arranged to bear on the edge of the box, substantlally asdescribed.

2. The combination with the box A, of the sieve J having spout N theframe H, links I supporting said frame and arranged to swing the spoutover the edge of the box, lever L, pitman M connecting the frame andlever, and the cover of the box A constructed to form a stop for thelever, substantially as described.

In testimony whereof I affix my signature,

.in presence of two witnesses, this 23d day of March, 1893.
